摘　　要：由于技术的进步和生产要求的提高,变频技术被越来越多的使用在包括港口起重机械在内的起重设备中。在提高整机性能的同时,大量谐波的出现也给起重设备的运行带来较大危害。本文针对某港口出现的谐波问题,采用了有源滤波器对谐波进行处理,取得了良好的效果,具有广阔的应用前景。Due to technical progress and improvement of production requirements, frequency conversion technology is used by more and more in, including port lifting machinery, lifting equipment. It improves the performance of the machine, but at the same time, a large number of harmonic also emerges and bring large harm to the operation of the hoisting equipment. In order to solve the harmonic problems for a certain port, this paper adopts the active filter for harmonics and achieves good effect.
